Went to street legals last Sunday and my 69SS launched great, pulled hard until about 1000 feet, then fell on it's face. Every pass. Best time was [email protected] 1.62 60ft. Usually runs easy mid 11's or quicker. Ran great last year on same fuel setup, only thing I changed was jetted down the primaries from 76s to 72s but that shouldn't cause it to lean out like that or would it? Holley 140gph electric pump, Aeromotive regulator with return line, 6an lines. 950 Quick Fuel with jet extensions. I noticed my fuel pressure was only 2psi after my first pass so cranked it up every pass which improved the times but still something wrong here. Last year was set at 6.5psi. No idea how it would change but I am no tuning genius. Eventually left it at 7psi. Fuel filter is new so I have no idea wth is wrong. One more track day this coming Sunday so want it to work. Any ideas gentlemen?
